SPECIFICATION forming part of Letters Patent No. 685,466, dated October 29, 1901.

Application tiled December l5. 1900. Serial No. 40.027- (No model) To all whom, t may concern:

Be it known that I, EDWIN BEADSHAW, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful lm provements in Window s, of which the followingis a specification.

This invention relates to that class ot' windows in which the upper and lower sliding sashes are capable ot' swinging inwardlyinto the room to permit the same to be conveniently and safely cleaned or repaired from the inside of the building. A window of this kind is shown and described in Letters Patent of the United States No. 589,242, granted August 31, 1897, to Lewis S. Bradshaw.

The object of my present invention is to improve the construction of the attachments by which the lower sash is detachably hinged tothe frame.

In the accompanying drawings, Figure 1 is a perspective View of a window embodying my invention and showing the sashes in their normal position. Fig. 2 is a fragmentary perspective view, on an enlarged scale, of the frame and the lower sash, showing one of the pivoted hinge-hooks in its operative position preparatory to being engaged by the hingesocket of the lower sash. Fig. 3 is a horizontal section of the same parts, taken immediately above the hook. Fig. 4 is a fragmentary vertical section taken centrally through one of the hinge-sockets of the lower sash, showing the corresponding hook engaged therewith.

Like letters of reference refer to like parts in the several figures.

v A is the window-frame, and B O are the upper and lower sashes, which slide vertically in the frame in the custolnary manner.

D D are upper and lower hooks arranged on one of the jambs of the Window-frame, and E E are corresponding sockets or socket-plates secured adjacent to the face of the lower sash and adapted to receive the hooks D when the latter are in their operative position, so as to form hinge-joints therewith. Each socketplate E has a vertically-elongated opening which is provided at its edge With an inverted- U-shaped lip or iiange @,which extends around the top and sides of its opening and projects beyond the face of the plate suiciently to overhang the head of the corresponding hook D and form an undercut socket'for the reception of the latter, as shown in Figs. 2 and 4. As shown in Fig. 4, the lower portion of the socket-plate is preferably arranged inwardly beyond the plane ot' the upper portion thereot1 and is countersunk flush with the face of the sash-rail. The hooks a' re constructed to swing out of the way ofV theV socket-plates E when not in use, so as to not interfere with the usual sliding movements of the sash. this movement of the hooks, each of the same is pivoted to swing horizontally. by means of vertical pins or trunnions d, arranged on the upper and lower sides thereof and journaled in bearingsf. These bearings are preferably formed integral with a faceplate F, secured to the adjacent jamb of the Window-frame and provided between its bearings with an openingf` through which the tail of the hook passes. This opening is provided on its inner side with a marginal rim f2, which is seated in an opening of the jamb, as shown in Fig. 3. By this construction the hook can be swung toward the sash to a position in which its head stands in the path of the corresponding socket E, as shown by full lines in Figs. 2, 3, and 4, or swung into the dotted position shown in Fig. 3, in which it clears said socket. The hook is yieldingly held in either of its positions by a spring g. The shank of this spring is driven into the jamb and confined between the jamb and the rim f2 of the face-plate F, and its free end is arranged to bearagainst the tail end of the hook when the latter is in its inoperative position and against the curved back of the hook when the same is in its operative position, as shown in Fig. 3. Each hook is provided with a head d', which is adapted to enter the undercut portion of the corresponding socket E, and adjacent to its head with a groove forming a neck d2, which enters the outer contracted portion of the socket, as shown in Fig. 4, thereby coniining the head of the hook in its socket. As shown in the last-mentioned ligure, the lower open end of the socket is fiared to facilitate the entrance of the hook.

The hooks D are preferably located a short distance above the sockets E in the closed po- To permit ofv IOS) sition of the lower sash, so that the sash must be partly raised to bring its sockets in line with the hooks.

The lower portion of the window-stop at 5 that side of the frame opposite the hooks D is made removable, as is customary in windows of this class and as shown in the Letters Patent hereinbefore referred to, and the sashcord on the same side of the window is de- 1o tachably secured to the sash by any suitable or well-known attachment, so that upon removing said stop and detaching said sashcord the lower sash can be swung into the room. Before swinging this sash inwardly the same is raised to bring its sockets E above the hooks D. The latter are then turned to their operative position, as shown in Figs. 2 and 3, and the sash is lowered, so as to engage its sockets over the heads of the hooks, as

2o shown in Fig. 4. The hooks now support the sash, and the latter can be swung inwardly on the hooks. After cleaning the window the same is swung outwardly to its normal position, the sash is raised sufficiently to disengage its sockets from the hooks, the latter are Turned to their inoperative position, as shown by dotted lines in Fig. 3, and the detached sash-cord and window-stop are finally replaced.

3o By my improved construction the hooks' D can be brought so closely to the sockets of thc lower sash as to insure their positive engagement with the sockets E before the sash is swung inwardly, thus hinging the sash to the jainb before its swinging movement takes place and avoiding all liability of dropping the sash in swinging it.

In combined sliding and swinging windows of this kind it is customary to couple the upper sashto the lower sash and swing both of the sashes into the room. For this purpose the upper portion of the parting-strip on the same side of the window-frame as the removable window-stop is made detachable and the adjacent cord of the upper sash is also made detachable in a well-known manuel'. The sashes may be coupled together by any suitable means-for instance, a keeper or swinging latch like that shown in Letters Patent No. 589,242, hereinbeiore referred to. 5o

I claim as my inventionl. The combination with a Window-frame, of a sliding sash guided therein and provided on its inner face with a socket which is closed at its upper end and open at its lower end and formed by a plate having on its face an undercut lip of inverted-U form, and a horizontally-swinging hook pivoted to the windowframe on the inner side of said sash and having a head constructed to enter the open lower 6o end of said socket and engage behind said undercut lip, and provided on the inner side of said head with a groove constructed to receive the vertical edges of said lip, substantially as Set forth.

2. The combination with a window-frame, of a sliding sash guided therein and provided with a socket which is open at one end, a horizontally-swinging hook pivoted to the jamb of the frame and capable of being turned into 7o or out of the path of said socket, and a retaining-spring arranged to bear against said hook, substantially as set forth.

3. The combination with a window-frame, of a sliding sash guided therein and provided with a socket which is open at one end, a horizontallyswinging hook pivoted to the jamb ofthe frame and capable of being turned into or out of the path of said socket and provided in rear of its pivot with a curved tailpiece, 8o and a spring arranged to bear either against the end or the back of said tailpiece for retaining the hook in either of its positions, substantially as set forth.

lVitness my hand this 11th day of Decem- 85 ber, 1900.
